cannot save table, duplicate field name (corruption?)

[mary]

Does this sound like a corruption problem?

I added a new field to a table, and saved the table. When the table is reopened, the new field is not there! I thought perhaps I forgot to save the field, so I tried adding the field again. When saving, the error said, "cannot save duplicate field name"?????

I I go to tools\options and click the "show system objects" the field will show up??

Do you think the best course of action is to import all the objects into a new db and try again?

Thanks for your help.
